A bus carrying more than 30 people hit a concrete overpass at Miami International Airport today, killing two people on board and leaving three others critically injured. The bus was too tall for the 8-foot-6-inch entrance to the arrivals area, said airport spokesman Greg Chin. Buses are supposed to go through the departures area, which has a higher ceiling, he said. Two large signs warn drivers of large vehicles not to enter beneath the concrete overpass.

Three people were at hospitals in critical condition. The other 27 passengers had been hurt, but their injuries were less extensive, authorities said. The bus was privately owned and typically used for tours, though police believe all the passengers were local residents, not tourists. The bus' ultimate destination was not yet known, but the driver (who survived) was unfamiliar with the area near the airport and did not intend to wind up at the arrivals area, police said. The bus was going about 20mph when it hit the overpass.
